Problems solved by technology

[0004] With people's understanding and attention to environmental protection, it is found that many cleaning agents used in the SMT manufacturing process are not only single-function, many types, difficult to manage, but also flammable and explosive, and some are toxic and volatile, which is harmful to the environment. Environmental and operator health adverse
Therefore, the requirements for the operating environment are high, otherwise there will be greater safety hazards, improper control, and safety accidents will occur from time to time

Abstract

The invention discloses a multifunctional water-based cleaning agent, which consists of the following raw materials in percentage by weight: 7 to 14 percent of propanediol methyl ether acetate, 5 to 15 percent of diethylene glycol monobutyl ether, 1.5 to 5 percent of monoethanolamine, 0.5 to 2 percent of octyl phosphate, 0.1 to 0.3 percent of defoamer, 1.5 to 5 percent of ethanol and 62.2 to 81.4percent of water. The multifunctional water-based cleaning agent is environment-friendly, high in safety, non-toxic, non-corrosive, pollution-free, low in using cost, safe and stable, has multiple cleaning functions and is used for cleaning red gum, solder paste, rosin, printed circuit board (PCB) carriers and the like.

Description

technical field [0001] The invention relates to the technical field of cleaning agents, in particular to a multi-functional water-based cleaning used in the SMT (Surface Mount Technology) manufacturing process, from red glue printing to DIP package welding, red glue, solder paste and rosin cleaning agent. Background technique [0002] In the SMT manufacturing process, in the process from red glue printing to DIP soldering, it is used to fix the copper screen after printing with red glue, the solder paste steel plate after printing solder paste, the residual rosin on the PCB after reflow, and the condenser of the reflow furnace After DIP wave soldering, the rosin on the PCB, the wave soldering furnace and the carrier of the PCB all need to be cleaned. [0003] Red glue, solder paste, rosin or patch glue in SMT manufacturing are complex in composition, containing various water-insoluble components such as resin, active agent, thixotropic agent, tackifier, etc., need to be cl...
